Screen(s) froze in Gnome-shell.

[KML]

Screen(s) froze in Gnome-shell when i was working in rdesktop.

The laptop (Dell E6520) was seated in a dock with 2 screens attached. Both the screen with rdesktop and the one without froze, and i was only able to move the mouse-pointer.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem!

[amirandom (random-w)]

I was playing Dota 2 and all the screen frozen.
After reboot i only could move mouse pointer after the login screen.
And i couldnt see my Desktop.

I solve this problem reinstalling Nvidia card driver and unity.

[KML (zemoh)]

I worked arround the problem by running rdesktop with the -b flag - Info from rdesktop man: "-b : Force the server to send screen updates as bitmaps rather than using higher-level drawing operations."

Since i did this i havn't had this problem even once, but it takes a heavy toll on the bandwidth, and on slow connections this is far from ideal.

Hope you find a fix.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 14.04 (trusty) reached end-of-standard-support on April 25, 2019.

Does this bug report have any relevance when using a currently supported version of Ubuntu? Please let us know if it does otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
